Product Overview

IOTA 2050 is a reactive single-ended hydroxypropyl silicone oil designed for advanced polymer modification. Its molecular structure features a silicone backbone on one end and a reactive hydroxypropyl group on the other, allowing it to be chemically incorporated into polymer systems as an active component.

Compared with conventional dihydroxy silicone oils, the single-ended functional design of IOTA 2050 enables more controlled distribution of silicone segments within the matrix, delivering enhanced surface properties such as improved hand feel, anti-graffiti performance, and release behavior.

Chemical Structure and Features

IOTA 2050 is a linear organofunctional polysiloxane with a primary hydroxyl group at one terminal end. This structure provides:

• High reactivity: The terminal hydroxyl group can react with isocyanates, carboxyl, epoxy, and other functional groups, making it suitable for polyurethane, polyester, and reactive coating systems.

• Excellent surface performance: Silicone segments reduce surface energy, improving smoothness, slip, and anti-adhesion properties.

• Directional functionality: The single-ended structure promotes silicone enrichment at the surface, enhancing anti-graffiti, release, and stain resistance.

Performance Advantages

1. Enhanced Surface Feel
   Incorporation of IOTA 2050 significantly improves surface smoothness and softness without compromising the mechanical properties of the base polymer.

2. Superior Anti-graffiti and Stain Resistance
   The silicone-rich surface layer reduces ink and contaminant adhesion, making surfaces easier to clean and maintain.

3. Effective Internal Release Performance
   IOTA 2050 can function as an internal release additive in polyurethane and polyester systems, reducing mold fouling and improving demolding efficiency.

4. Excellent Compatibility and Stability
   As a reactive silicone oil, IOTA 2050 becomes chemically bonded into the polymer network, minimizing migration and ensuring long-term performance stability.
